HOSE-COUPLING.

lZDCIFCATIQN forming part of Letters Patent No. 339,109,l dated March30, 1886.

Application iilcd September 14, 1851.5.

T0 all whom, t may concern:

Be it known that I, (3i-Lunnis A. MUDDI- MAN, of \Vasliington, in theDistrict of Columbia, have invented certain new and useful Improvementsin Hoseouplings; and I do hereby declare that the following is a full,clear, and exact description thereof, reference being had to theaccompanying drawings, in which- Figure l is a perspective view of t-heparts of my coupling separated from each other. Fig. 2 is a like view ofthe saine united. Fig. 3 is a central longitudinal section ot' saidcoupling. Fig. 4 is a perspective view of a suppleinental plug for useupon the plug of an ordinary street-washer, and Fig. 5 is a verticalcentral section of the same.

Letters of like name and kind rel'cr to like parts in each oi' thefigures.

In the use ci' hose for liquids it has heretofore been customary, inconnecting two pieces together7 or when connecting the hose with a plug,to employ couplings having square abutting ends, and to depend upon anelastic washer placed between the same for the production of a joint,but such nie-ans have proved defective, especially in connection withhose employed for natering lawns, sprinkling streets, 83e., which isusually manipulated by inexperienced persons;

rlhe object of my invention is to enable a joint to be easily andquickly made between sections oi` a hose or between a hose and a plug;and to this end said invention consists in the construction andcombination of parts, substantially as and i'or the purpose hereinafterset forth.

In the carrying of my invention into practice athiinble, A, having theusual grooved periphery is inserted into the end oi'a hose, B, andconned therein by wire C, wound around the exterior of said hose, or byany other means ordinarily employed. The projecting end a of the thimbleA has a general bell shape, and within its interior is provided with aconical face, c', that at its inner end is merged in the axial openingc'l of said sleeve. The opposite thimble, or, if part of a hydrant, theplug D, has a conical face, d, formed upon its end, which face cor1esponds to and is adapted to it within said conical face c', wherebythe axial opening d/ within said plug will be caused to coincide SerialNo. 177,077. (No mo lol.)

with and form a continuation ol' said opening a. The periphery oftheplug` 1') is somewhat larger in diameter than the end ot' the thimble A,and is provided with a screwj thread, di, and over the same is fitted asleeve, E, which is threaded interiorly. Said sleeve is swiveled uponsaid t-himble A, in the usual way, the latter being` provided at its endwith a radially outward projecting iiange. a3, that is engaged by aradially inward projecting flange, e, which is formed at the upper endci said sleeve. If, now, the hollow conical end ofthe thinlble A isplaced over or upon the con' ical end ofthe plug D, and the sleeve lllscrewed down around the latter, said parts will be firmly boundtogether, and their bearingi'aces c and d will be held in contact.

In order that a tight joint may be formed between thefthimble A and plugD, I place between t-he faces a and d a rubber washer, F, which conformsto the shape of said faces, and by the action ofthe sleeve E iscompressed between the same.

To prevent displacement and loss of the washer F, it is loosely attachedto the thimble Aby means of a rib, j', that is formed upon the peripheryat the upper end of said washer, and lits into a correspondingcircumferential recess, at, which is provided within the axial openinga2 of said thiinble. Th us constructed, said washer may be readilyplaced in or removed from position when desired, as its enlarged part iseasily compressed while passing through the neck of said recess ct; butthe connection between said parts is suflicient to prevent theiraccidental separation during any ordinary use of a hose.

It will be seen that, if desired, the elastic washer F may bc readilyattached to the plug D instead ot' the thimble A, for which purpose itwill only be necessary to provide a rib at the lower end upon the innerside of said washer and a corresponding groove within the periphery ofsaid plug.

For use with an ordinary street-washer, I employ a supplemental plug, D,(shown in Figs. et and 5,) which is like the plug D, before described,except that instead of the grooved lower end for insertion within a hosesaid plug Dhas within its lower portion a threaded interior, d3, that isadapted to fit over the IOO plugof such streetfwasher. Said plug D',after havingrbeen placed in position, need not be removed with the hose.Y

I-Iaving thus described my invention, what I 5 claim is- 1. Incombination with the female part of a coupling having the conicalbearingsurface and au annular groove beyond such surface, the hollowconical elastic Washer fitting over 1o the bearing-surface and providedwith an annular rib to engage the groove Within the coupling,substantially as and for the purpose specified.

2. A hose-coupling provided with corre- IS spending male and femaleeonicahbearingsurfaces, in combination with a conical elastic washeriitting and adapted to be compressed between such bearing-surfaces, andhaving a portion interlocking with a part of one ofthe coupling` halvesbeyond the bearing-surface 2o thereof, so as to attach it to such partof the coupling, substantially as and for the purpose described.

3. The thimble A, having the conical face c and circumferential recess aWithin, and 25 the threaded sleeve E, journaled upon said thimble, incombination with the plug D, provided With the conical face d andthreaded exteriorly, and with the conical elastic Washer F, having therib j, substantially asl and for the purpose shown and described.

In testimony that I claim the foregoing I have hereunto set my hand this7th day ol' September, A. D. 1885.
